For each kernel release where commands or events are added to the
management interface, the revision field should be increment by one.
The increment should only happen once per kernel release and not
for every command/event that gets added. The revision value is for
informational purposes only, but this simple policy would make any
future debugging a lot simple.

Currently, mac80211 uses the power constraint IE, and reduces
the regulatory max TX power by it. This can cause issues if
the AP is advertising a large power constraint value matching
a high TX power in its country IE, for example in this case:
...
Country: US Environment: Indoor/Outdoor
...
Channels [157 - 157] @ 30 dBm
...
Power constraint: 13 dB
...
What happened here is that our local regulatory TX power is
15 dBm, and gets reduced by 13 dB so we end up with only
2 dBm effective TX power, which is way too low.
Instead, handle the country IE/power constraint IE combined
and restrict our TX power to the max of the regulatory power
and the maximum power advertised by the AP, in this case
17 dBm (= 30 dBm - 13 dB).
Also print a message when this happens to let the user know
and help us debug issues with it.

CMD_MAC_CONTROL is currently sent async to the firmware, and is sent
from the lbs_setup_firmware() path during device init.
This means that device init can complete with commands pending, and
the if_sdio driver will sometimes power down the device (after init)
with this command still pending.
This was causing an occasional spurious command timeout after init,
leading to a device reset.
Fix this by making CMD_MAC_CONTROL synchronous when called from the
lbs_setup_firmware() path.

"adapter->bss_prio_tbl[j].bss_prio_head" points to linked list of
interfaces with priority 'j'. "bss_prio_tbl[j].bss_prio_cur" is
supposed to point to next interface every time the routine for
dequeuing the packet is called. This ensures that each interface
gets fair chance.
Currently we have AP and station interfaces with priority '0'.
Therefore "adapter->bss_prio_tbl[0].bss_prio_cur" should
alternately point to AP and station nodes. Since "bss_prio_cur"
is not correctly updated, for each packet picked for AP, two
packets are picked for station interface.
This patch fixes the problem by correctly updating "bss_prio_cur".

Currently AP interface has higher priority over station. Hence
separate entries are created in "adapter->bss_prio_tbl" for these
interfaces and station packet is dequeued only if there is not
packet in queue for AP. It is observed that ping for station
interface doesn't work if heavy traffic is running on AP.
The problem is fixed by having same priority for both the
interfaces. This patch also removes an extra initialisation
for "priv->bss_priority".
